Specification of Letters Patent.

To Il ie/wm, it may concern:

.le 1t known that l, S'rnrimN S'rnraNr.\N, a citizen ol the UnitedStates. residing at Columbus, in the county ot Franklin and State otOhio, have invented certain new and uset'ul lmprovements 1nCoal-lthishers,

olf which the vfollowingis a speciieatiou. reference being had thereinto the aecompanying drawings.

'lhis invention relates to coal washing devices in which the separationol. the im purities or refuse matter ell'eeted by subjecting thematerial `in the washing tank or vessel to agitation, or the action o1water currents, or both, and the principal object ot' the invention isto provide automatically loperating devices for periodically drawing ordischarging the refuse iratter.

lllhe inventionis well adapted for use `in connection with coal washersof the type showlrin Patent No. 702,897 granted June 17, 1902, and inthe accompanying drawings 1 show it embodied in a coal washing machineof this kind.

Of the drawings Figure 1 is a side eleva` tion oitl the valve actuatingmechanism, with the refuse chamber and valves shown .in sec tion. Fig. 2is a horizontal section taken along the line 2-2 of Fig. 1. Fig. 3 is anend elevation of the valve actuating mechanism, together with the lowerparts of the washing mechanism proper. Fig. 11 is a side elevation ofthe valve actuating mechanism opposite that shown in Fig. 1. Referringto the drawings, A is a washing vessel vor tank of .suitable form havinga contracted lower end. Preferably it is ot' the truste-conical formshown. At its upper end the vessel A is open and adapted to receive thecoal or other material to be washed. The material'may he fed in anydesired manner to suit the requirements of the Washer in its speed ofoperation and the withdrawal of WashedA or separated materialtherefrom.v l

F is a Water chamber or ring surrounding and attached to thelower end ofthe washer, communicating therewith through a. perforated Wall or platef and water supply pipes F. The Water thus supplied to the Washer isafter the washing operation conducted away, with the lifted or suspendedlighter or finer impurities or separated materials, by an opening a nearthe top of the Washer and suitable conduits.

f The eh; aber F has a short downward cylindrieal extension Ff.terminating in a horizontal flange ji. lolted to the latter is ahorizontal 'trame which l term the valve- 'fraaie lt is east andlinished in the form shown in Figs. 2, 3, .t and 5. 1t comprises ahorizontal web or plate .f/, having a central aperture g in line withthe chamber of the extension F2, which web is secured to the tlange olthe latter by the bolts (/2. Between the holes t'or said bolts thel'rame is lormed on itsl under side with a` longitude nal recess gt,extending -trom end to end ol the trame and adapted to receive betweenits side walls g a closely-fitting valve ll', formed with an aperture Lcorresponding with that at g in the valvedrame. The valve may be movedlongitudinally by means hereinafter' described, so that. its aperture/1/ may coincide with the aperture g to permit the esca pe ot materialfrom the washer, or so as to lie beneath the imperforate plate f/ andbring the imperfoi'ate portion /f ojt the valve across the aperture g totightly close this` exit from the washer.

.l is a plate cooperating with frame (l to closely hold the valve llexcept as to its longitudinal movement above described. lt. lies beneaththe valvealirame and is secured to the latter by bolts 'i along itssides. The bolts g2 hold securely together notonly the horizontal flangef, the valve trame G and the bottom plate 1 but also pass through andfasten to these several parts, the uppertlang@ l ot the pipe whichsurrounds the refuse chamber Ll, A lower valve mechanism 5 similar inall respects to the upper valve mechanism, alraidy described, isarranged at the lower end ot' the pipe 2 and secured thereto. lnalinement with the pipe 2 and upon the lower side ot'V the valvemechanism 5 is secured the discharge nozzle 6.

The entire machinery is supported on two cast. iron vertical side frames37 having all the. necessary bearings east thereon with removable caps.The gib plates 31 and 32 attach the two frames together in a substanptial way.

The upper valve is opened and closed by a in the Aframes 37. lhe hub otcrank 12 is complete revolution of a crank 12 which is loose on shaft15., The hub of the-adacent crank 13 is key-seated on shaft 15 and thetwo cranks are attached by' a breaking pin vserious injury tothemarchine. A spur'pm-- ion 17 is alsomounted on the `shaft 15. Thisspur pinion meshes with an intermittent gearv 18 which is twice thediameter vof the lSpur bar 8".

but has the same numberof teeth as' pinion,

1t" is mounted on shaft 19,

thev pinion.

which l1s revolubly Supported in bearings 19', 19 formed inv frames 37.Below this intermittent .gear there is mounted another spurpinion 21with the same number of teeth land diameter as spur pinion`17. Thispinion which is mounted on' a lowershaft 24 is also in position-to meshwith. theteet-h of the intermittent, gear. Shaft 24 is rev# olubly`supported in bearings 24', 24 formed in side frames 37. At its end.there is secured another crank 12 which is attached to the lowervalvegby a connecting When the intermittent gear revolves in thedirection indicated by the arrow it engages the upper spur inion 17 andgives the latter a complete revo ution., The crank 12, being on .thesame shaft, also makes a complete revolution and thus gives irst abackward and, then a forward movement of reciprocationto the connectingrod `8 and, by means of it, to the upper valve H. During the 'l backwardmovement of the crank the valvge opens land permits the refuse which hasaccumulated *in the .bottomv of the washer tank A to drop into'refusechamber 4. By the forward movement loit the v,crank the valve is closedand the refuse is trapped be4 tween theupper and the lower valves.'

When the intermittent gear disengages. from the upper pinion 17 .itengages immedi `ately the lower spur pinion 21 and gives a completerevolution to it also. The crank.

' 12.at.the end of this shaft byL its rotation opensand closes the'lowervalve 5; Thus the Arefuse which `was trapped in refuse chamber 4 isdischarged through the nozzle 6. On the intermittent gear shaft 19 thereis mounted a spur pinion 2O. This .pinion meshes with aA spurrv gear 22which has four times as many teeth as. the spur pinion 20. When. thespur gear22 makes one. quarter 'of a revolution the; spur pinion Q().makes one complete revolution and turns the intermit tent gearthrough one revolution also. Thespur gear 22 is keyed upon-shaft 25which is mounted in bearings 25 formed in the side frames 37, 37. .Astar wheel 23 with four notches is also mounted on shaft 25. The notchesof this star wheel are engagedy by steel rollers 39 whichl are"Arevolubly 'lated from one minute' to twelve minutes by maliens l.mounted on pins 40. Each of these pins is securedbetweentwo of the lugs41 on disk wheel 26. This disk wheel has twelve equally spaced pairs oflugs 41 apertured to receive and support the pins 40.

- The drawing shows the disk wheel 26 with but one -roller39 and pin 40mounted thereon, f

the roller being just/about to engage a notch of the s ta-r wheel. Thisroller 39 gives4 a quarter revolution to the star wheel and shaft 25.The spur gear 22 being keyed to the A sameshat alsomakes a quarterrevolution, and it gives a complete revolution to the intermittent-gearshaft 19 by means of the pinion 20. `When theintermittent, gear makes acomplete revolution it first meshes with the upper spur vpinion 17opening and closing the uppervalve-H, and then, disengaging from theupper pinion, it engages'the lower pinion 21', which --in turn makes acomplete revolution and ,opens and closes the lower valve 5. -After theintermittent gear disengages from the lower pinionv it remains in theyposition shown in Fig. 2 until the roller on the disk wheel nextengages and gives another quarter revolution tothe star Awheel 23.

Assuming that revolution' in twelve minutes, the interval between thedraws of refuse can be reguadjusting in positionv as many rollers on-thedisk wheel as may be required. 28 on which the disk lwheel is mounted issupported in bearings 28 in the side frames `37, and has a'worm wheel 27secured 'to it.

The-worm 29 which drives this worm wheel is rigidly mounted on avertical shaft 33, which is held in place by the vertical bearing V31and step boX bearing 32. These bearin s are formed in the cast gib plateextensions 31 and 32 respec'tivelyLwhich are the disk wheel one. i

The' "Shaft bolted to the supporting side frainesf-37of` Y the machine.A bevel gear 34 ismcunted at the upper end of this vertical 'shaft' 33which meshes withthe bevel pinion 34,l the' latter being kmounted on'shaft 35. This .shaft is provided at itsv end with a driving sprocket36 of such diameter as to give the proper speed to the valvemechanism;`This i sprocket receives-its powerby chain belting from any suitablelpower source and transmits it to the valve operating device.

By the mechanism voimy invention, means is provided for automaticallyoperating the upper valve and the lower` valve of a refuse -chamber atdeniteintervalsg These inteigvals are at the Sametime adjustable'to` jsuit the number of refuse draws necessary to clean coalof varyingquality and mixed with a varying amount of dirt and otherV lforeignmatter. For many reasons itis desirable to havethis' certainty of valveoperation at deiniteintervals of time.
